Description
Technical field:
The present invention relates to a kind of screw extruders, belong to plastic material production equipment technology.
Background technique:
Plastic granulating is a kind of technique of plastics machinery processing, is exactly the plastics various different shapes by melting, squeezing
Out, the processes such as pelletizing are prepared into graininess that facilitate following process, uniform.Screw extruder is that the core of plastic granulating is set
It is standby, by pressure and shearing force that screw rod rotation generates, material can be allowed sufficiently to carry out plasticizing and uniformly mixing, led to
Cross mouth mold molding.Therefore, screw extruder during plastic granulating, heat close by the general mixing that carry material simultaneously
Refining, the work squeezed out will affect whole product quality if one of Absent measures are bad.Existing screw extruder
Contain bubble in material after screw rod completes the process of stirring, mixing using the structure of straight tube, directly extrude cooling and dicing, make
It is poor at product quality.
Summary of the invention
The purpose of the present invention is providing a kind of screw extruder in view of the above problems, avoid containing in the product squeezed out
There is bubble, improves the quality of material grain.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of screw extruder, including body, the body are divided into batch mixing segment, heating melting section and heat preservation and squeeze out
Section, the batch mixing segment and the heating melting section are horizontally disposed, and the heat preservation extruding zone and the heating melting section are at downward 45 °
Overturning angle setting, the internal body are provided with the first screw rod being horizontally mounted, and the end of first screw rod is located at described
The junction of heating melting section and the heat preservation extruding zone is equipped with spiral bevel gear, and the spiral bevel gear is nibbled with helical gear
It closes, the helical gear connection is located at the second screw rod in the heat preservation extruding zone.
The screw extruder is provided with feed inlet on the batch mixing segment.
The screw extruder is provided with electric heater unit in the heating melting section.
The screw extruder, the heat preservation extruding zone are provided with insulating layer.
The screw extruder is provided with stirrer gear on first screw rod.
The junction of the screw extruder, the heating melting section and the heat preservation extruding zone is provided with exhaust
Mouthful.
The utility model has the advantages that
The present invention is arranged diagonally downward by extruding zone is kept the temperature, and material reaches heat preservation extruding zone later in the work of gravity and screw rod
It trickles diagonally downward under, is conducive to the bubble for excluding to mix in material, the material granule density squeezed out in this way is uniform, expects grain quality
It is high.
Detailed description of the invention
Fig. 1, structural schematic diagram of the invention.
In figure: 1, batch mixing segment；2, heating melting section；3, extruding zone is kept the temperature；4, the first screw rod；5, spiral bevel gear；6, tiltedly
Gear；7, the second screw rod；8, feed inlet；9, stirrer gear；10, exhaust outlet.
Specific embodiment
With reference to embodiment, the present invention is furture elucidated, it should be understood that following specific embodiments are only used for
It is bright the present invention rather than limit the scope of the invention.
As shown in Figure 1, a kind of screw extruder of the present embodiment, including body, the body are divided into batch mixing segment
1, heating melting section 2 and heat preservation extruding zone 3, the batch mixing segment and the heating melting section are horizontally disposed, the heat preservation extruding zone
It is obliquely installed with the heating melting section at downward 45° angle, the internal body is provided with the first screw rod 4 being horizontally mounted, institute
The end for stating the first screw rod is located at the heating melting section and the junction for keeping the temperature extruding zone is equipped with spiral bevel gear
5, the spiral bevel gear is engaged with helical gear 6, and the helical gear connection is located at the second spiral shell in the heat preservation extruding zone
Bar 7.
Screw extruder described in the present embodiment is provided with feed inlet 8 on the batch mixing segment.
Screw extruder described in the present embodiment is provided with electric heater unit in the heating melting section.
Screw extruder described in the present embodiment, the heat preservation extruding zone are provided with insulating layer.
Screw extruder described in the present embodiment is provided with stirrer gear 9 on first screw rod.
The junction of screw extruder described in the present embodiment, the heating melting section and the heat preservation extruding zone is set
It is equipped with exhaust outlet 10.
It should be pointed out that above-mentioned embodiment is only intended to clearly illustrate example, and not to embodiment
It limits, there is no necessity and possibility to exhaust all the enbodiments.Each component part being not known in the present embodiment
It is realized with the prior art.For those skilled in the art, in the premise for not departing from the principle of the invention
Under, several improvements and modifications can also be made, these modifications and embellishments should also be considered as the scope of protection of the present invention.
